Symbolic links

In computing, a symbolic link (often shortened to symlink and also known as a soft link) consists of a special type of  file that serves as a reference to another file or directory. Unix-like operating systems in particular often feature symbolic links.Unlike a hard link, which points directly to data and represents another name for the same file, a symbolic link contains a path which identifies the target of the symbolic link. Thus, when a user removes a symbolic link, the file to which it pointed remains unaffected. Symbolic links may refer to files even on other mounted file systems. The term orphan refers to a symbolic link whose target does not exist.
